Abiotic factors/Description of Ecosystem


· All orangutans live in the tropical/subtropical forests in southeast Asia
· Winds called monsoons are usually what control the climate of southeast Asia
ü Average tem= 18 degrees Celsius
ü Annual precipitation= 103 inch
ü Latitude range=10 degrees South 25 degrees north
· Rainfall is very heavy in each month. The total amount of rainfall is usually more than 100in
· With the high surface and humidity it causes cumulus clouds to form early in the afternoons, pretty much everyday
· Orangutans live in Borneo lowland and Montane forests, Kinabalu montane shrub lands, and sundaland rivers and swamps.
· Orangutans that live in the wild have been observed making tools to scratch themselves, while using leafy branches to shelter under. Released captive individuals are reported to use sticks for digging, fight prying, eating scratching, and many other purposes.

Endangered Orangutan


· this problem is caused by commercial logging, and forest clearance for oil palm plantations and agriculture
· they are animals that live in trees
· there are two types of orangutan species, Bornean and Sumatran
· Sumatran- eat more fruit and insects

Threats to the Orangutan


· Orangutans have lost about 80% of their habitat in the last 20 years
· We lost about 1/3 of the wild population from the fire in 1997-1998
· There are about 54,000 orangutans left in Borneo and about 6,600 left in Sumatara
· Logging for timber and oil palm plantation are expected to kill of 98 more percent of the orangutans by 2022.

Importance of the Ecosystem

The rainforests in Southeast Asia are the oldest rainforests on earth. They date back to the Pleistocene Epoch 70 million years ago. We depend on these rainforests for logging, palm oil, and agriculture. All the animals that live there depend on these rainforests for their habitat and for all their resources. The dipterocarpaceae tree is a habitat for the orangutan and many other animals; it can get up to 130 ft high. We also get some of our food from this rainforests; there are many different types of fruit trees in the Southeast Asian Rainforests.


Conservation plan

Saving these orangutans is very important; they are a crucial part of their ecosystem. Purchase recycled paper and products made from sustainable timber. Habitat destruction continues to put orangutans in danger. Eco-labeling (labeling that indicates whether the product is green or not) can be non-consistent so it’s best to not buy anything that’s made with tropical hardwood. In addition do not waste paper. Also buy only products with no palm oil or products that have sustainable palm oil. Palm oil plantations have appeared all over the great ape's habitat. Many plantations consider orangutan’s pests and kill them when given the chance.
